flint54 Posted November 18, 2011 Share Posted November 18, 2011 Swapped in a K&N cone system (FIPK) tonight, and found something that really surprised me. One of the tabs on the outboard side of the stock airbox had been making contact with the harness that feeds the PCM. The tape wrap was rubbed through, and the insulation on one wire was halfway rubbed through. Not sure which wire, but my guess is they're all important. If you have a stock airbox, check this out. If close, recommend adding some form of chafe wrap. Yes, the airbox was tightly mounted. BTW, the FIPK system is dimensionally incompatible with a throttle body spacer. Hood won't close. You can have one or the other, but not both. Link to comment Share on other sites More sharing options...
91Pioneer Posted January 1, 2015 Share Posted January 1, 2015 I found this via a search. I have the same problem, one of the clips from the airbox has rubbed into the PCM wiring harness. It caused hard starting and a misfire for me today as I was working with the cooling system and removed the airbox lid during that. Stupid, stupid design, a metal clip can rub right through wiring to the PCM. Jeep/Chrysler should have damn well known better. Oh well guess I'll add fix PCM wiring to my to-do list.... at least I was able to wiggle the wiring and get it running like normal LOL Link to comment Share on other sites More sharing options...
